项目摘要

In the first term of this IRC program, we developed and demonstrated a reliable technique to reduce hydrocarbons by over 90% at six sites polluted with gasoline or diesel. The goal of the second term of this IRC is to develop approaches that will further reduce hydrocarbons in soil to minimal levels. We hypothesize that there is an optimal balance of fertilizer components such as phosphate, magnesium, citrate, sulfate, iron, and nitrate that will stimulate a robust degrading microbial community. We will develop new ways to calculate what this optimal balance across the many different Prairie soil types. To develop the new calculations, we will identify the balance of microbes and ions associated with successful remediation and then create a new fertilizer mix that will stimulate successful remediation across western Canada. We hypothesize that organic or fatty acids added to the biostimulatory solution may be critical to this trace remediation, or that there is an organic phosphorus compound associated with trace remediation. Alternatively, the interactions between microbes and minerals may increase in importance at very low hydrocarbon concentrations and we need to understand how minerals control remediation. The first IRC term provided training for 36 personnel, of which 20 were women, and the second phase envisions training an additional 19 to 40 personnel. Students readily found employment in the environmental sector because the students work closely with industry, building soft skills and a business network. In so doing, the IRC program provides an ideal bridge for students to cross from their academic training to employment in their chosen field of study. At the conclusion of this second term of the IRC, we will have developed, deployed and validated an economically viable method

在这个 IRC 项目的第一学期，我们开发并展示了一种可靠的技术来减少六个受汽油或柴油污染的地点的碳氢化合物含量超过 90%。本次IRC第二届任期的目标是开发将土壤中的碳氢化合物进一步减少到最低水平的方法。我们假设肥料成分（例如磷酸盐、镁、柠檬酸盐、硫酸盐、铁和硝酸盐，将刺激强大的降解微生物群落。我们将开发计算多种不同草原土壤类型的最佳平衡的新方法。为了开发新的计算，我们将确定与成功相关的微生物和离子的平衡修复，然后创造一种新的肥料混合物，这将刺激整个西部地区的成功修复加拿大。我们假设添加到生物刺激溶液中的有机或脂肪酸可能对此至关重要痕量修复，或存在与痕量修复相关的有机磷化合物。或者，微生物和矿物质之间的相互作用可能会在非常低的情况下变得更加重要。碳氢化合物浓度，我们需要了解矿物质如何控制修复。第一期 IRC 培训了 36 名人员，其中 20 名女性，第二期预计再培训 19 至 40 名人员。学生很容易在环保领域找到工作因为学生与行业密切合作，培养软技能和商业网络。这样做， IRC 项目为学生从学术培训到就业提供了理想的桥梁他们选择的研究领域。在 IRC 第二任期结束时，我们将开发、部署和验证一个经济可行的方法
